Time to Start the War! Now the Cavalry Battle! And the Great Uprising!

S1 E22: It's the day of the Athletic Meet and excitement is running high… For all but Tenma, that is. You see, Karasuma hasn't been in any episodes as of late! Back to the sporting event, which isn't turning out to be very sporting at all!?! Classes 2-C and 2-D have turned this fun-filled day of activities into a very personal death match, centered around the feud between Karen and Lara. The final event: The traditional school cavalry contest! (Talk about triangles!) Seething rivalries are acted out upon the field of battle as the teams are knocked out, one by one. And in a surprise plot twist Eri will sacrifice herself to save Harima's pride!?!
